Grocks

Grocks are the enemies of the game and come in many shapes and sizes, though most resemble boulders with stubby legs, which oddly enough resemble human feet. They are rock monsters that began terrorizing the West. No one knows why. They attack en masse at the blast of a foghorn. A rare few have arms (Gungrocks and Diggrocks) or lack legs altogether (Springgrocks and Ultimogrock). They are characterized by their appearence when the sky turns red, preference to attack in waves of three, and their love of Scrogs, the various villages' livestock. There are a total of 40 species of rock, three of which are barrels (which are not true grocks but have the defense of them). Grocks have "bones" but they are just stones. If you can 5-star every stage then you can view a gallery of all the grocks that appear in the game from Sal's Grock Collection. They reappear in Dillon's Rolling Western: The Last Ranger but with also additional grocks, that go after the Train and/or rare occurances in Treasure Hunts.
